This partnership opportunity focuses on advancing the components and subsystem technologies necessary to implement a constellation of low-cost, low Earth orbit, small satellite atmospheric occultation instruments that meet or exceed the retrieval capabilities of SAGE II (Stratospheric Aerosol and Gas Experiment II). The goal of this effort is to sustainably meet NASA's ongoing mandate to monitor ozone in the atmosphere while simultaneously advancing the state of the art, overcoming the geographic sampling limitations of the SAGE series of heritage instruments, and preserving the continuity of the SAGE data product. This requires observing the solar disk during sunrise and sunset occultation events in several spectral channels in the 350 nm to 1050 nm region. The proposed implementation utilizes a constellation of small satellites.
NASA Langley Research Center (LaRC) is seeking potential partner(s) having one or more of the following capabilities:
a) Focal plane detector - focal plane detector arrays (128 × 128 or 256 × 256 pixels) and 14 or 16-bit readout electronics with programmable integration time, sensitive to approximately 350 nm to 1050 nm with square pixel pitch, on the order of 1 to 5 million electrons full well, temperature controlled focal plane (non-cryo cooled), and capable of 64 Hz full frame readout rate.
b) CubeSat or small satellite spacecraft bus including structures and trusses for approximately 6U form factor, solar panel electrical power system with at least 25 Whr battery storage. System shall have command and data handling, (aggregate daily data volume of approximately 600 megabytes per day).
c) small satellite attitude determination and control system for a 10 kg 6U total package with at least 1.5 degrees per second slew rate and < 5 arcminute pointing accuracy with Kalman filtered dead reckoning (e.g., 3-axis accelerometer/magnetometer/rate gyros) and absolute attitude determination (e.g., star tracker).
d) CubeSat Integration of flight instrument into the spacecraft bus and any needed electrical component build and assembly.
This partnering opportunity does not guarantee selection for award of any contracts or other agreements, nor is it to be construed as a commitment by NASA to pay for the information solicited. It is expected that the partner(s) selected would provide (at no cost to NASA) conceptual instrument designs (with sufficient details to enable accurate mass, volume, power, and telemetry requirements), operational concepts, calibration and characterization definition and planning, payload constraints/interface analysis, technical risk analysis, and would agree to participate in cost and schedule analysis as part of the mission concept proposal.
Partner selections will be made by LaRC based on the following criteria:
1) Technical Capability. This criterion assesses the technical capabilities required for the performance of the development activity described herein with emphasis on the instrument components listed and CubeSat spacecraft integration and test.
2) Payload Accommodation. This criterion assesses the understanding of accommodating optical payloads. [Applicable to (b) and (d) only].
3) Facilities. This criterion evaluates the proposers facilities (development, testing, and analyses) to conduct the development or demonstration of the proposed task.
4) Cost. This criterion assesses the cost estimate for the space technology solution being offered.
5) Flexibility. This criterion weighs the ability of the proposer to customize the space technology solution to provide extensibility for future instruments in the constellation series.
RESPONSE INSTRUCTIONS:
Responses to this partnering synopsis shall be limited to eight (8) pages per item as defined in items (a) through (d), in not less than 12-point font. Responses must address each of the aforementioned evaluation criteria. All responses shall be submitted to NASA LaRC via e-mail by 4:00 PM EST on April 18, 2016 to: [email protected] and [email protected]
